A Pacifica man employed as a San Francisco Sheriff's deputy faces felony charges for robbing a bank of $1,700, authorities said.

Philip Chun Tong, 36, allegedly held up a Bank of America branch on the 3700 block of Balboa Street Nov. 7 with a note demanding cash. Investigators later found Tong's fingerprints on the note, according to San Francisco District Attorney George Gascon.

Police arrested the deputy Friday at his job in the city jail and have charged him with one count each of robbery and second-degree burglary. Attempts to reach Tong or his family were unsuccessful.

When Tong filed for bankruptcy in July he wrote he'd been in his job for seven years, is married and has two sons, five and seven years old. Tong said he makes an average of $7,300 per month working as a deputy. Sheriff's authorities said he's been placed on unpaid leave while the case makes its way through the court system.

Gascon said Tong's "conduct is deplorable and will be met with serious consequences."
